  Common Analytical Problems We   indicated   that   analytical   chemistry   is   more   than   a   collection   of qualitative   and   quantitative   methods   of   analysis.   Nevertheless,   many   problems   on which   analytical   chemists   work   ultimately   involve   either   a   qualitative   or   quantita- tive   measurement.   Other   problems   may   involve   characterizing   a   sample’s   chemical or physical properties. Finally, many analytical chemists engage in fundamental studies   of   analytical   methods.   In   this   section   we   briefly   discuss   each   of   these   four areas of   analysis. Many   problems   in   analytical   chemistry   begin   with   the ...

  Numbers in Analytical Chemistry Analytical   chemistry   is   inherently   a   quantitative   science.   Whether   determining   the concentration   of   a   species   in   a   solution,   evaluating   an   equilibrium   constant,   mea- suring   a   reaction   rate,   or   drawing   a   correlation   between   a   compound’s   structure and its reactivity, analytical chemists make measurements and perform calculations. In   this   section   we   briefly   review   several   important   topics   involving   the   use   of   num- bers   in   analytical   chemistry. Fundamental Units of Measure Imagine   that   you   find   the   following   instructions   in   a   laboratory   procedure:   “Trans...
